MANU FACTURE oF PAPER TUBING.

SPECIFICATION forming part of Letters Patent No. 365,815, dated J'uly 5, 1887.

Application filed March 20, 1856. Serial No. 195.913.

(No model.)

3 and 4t are cross-sections on the lines y fl/ and.

z z of Figs. 2 and 3, respectively.

The apparatus shown in these drawings is identical with that shown in Figs. 2 to 9, in-

2o elusive, of the drawingsof Letters Patent of the United States No. 331,721, granted December 1, 1885, except that the present appa ratus has some additional features, now to be explained.

Ais a steam-pipe extending from a steamboiler (not shown in thedrawings) to the under side of the rear part of the rectangular portion of the former B, where it communi- Cates with the cavity C. That cavity extends 3c from its connection with the pipe A directlyA over the central longitudinal Zone of the under side of the former B, as far forwardin that former as the dotted line z z. It there eonnects with a smaller angular cavity, D, and

the latter connects with the cavity E, which extends thence to the rear end of the former B, where it connects with the exhaust-pipe F. The new process is as follows: While the paper is being drawn over the former B and 4o folded and pasted together into a rectangular tube around the rectangular part of the former in the manner set forth in said Letters Patent, steam is being admitted into the cavity Ofrom the pipe A,and driven from that cavity through the smaller cavities D and E into the exhaustpipe F. The presence and passage of steam along the cavity O heats that wall of the former 'B which separates that cavity from that part of the surface of the under side of' the former against which the two borders of the paper 5o are being folded and pasted together. That heating dries the applied paste and dries the adjacent paper, and, indeed, it heats the paper sufliciently to dry tl1epaste,wl 1ich is soon after applied to the bottom folds of bag-blanks cut 55 from the continuous tubing, manufactured on the apparatus shown in these drawings.-

'When paper bags are made on the machine shown and described in LettersPatent of the United States No. 331,722, of December 1, 6o 1885, they require to be dried in a separate apparatus, as is plainly stated in those Letters Patent; but the use of my presentproccss entirely obviates such subsequent drying, and will enable that machine or any similar appa ratus to produce paper bags already dry enough to be packed for shipment.

I claim as my invention The process consisting in simultaneously drawing a continuous paper tube around and along a Vformer andl forcing a stream of steam through a series of cavities in that former, and

thus continually heating and drying the paper tube by means of heat passing from the steam through the walls ofthe former into the 'fibers 75 of the' paper, all substantially as described.
